No longer assigned (decommissioned 1940), entire route now part of MD 290.

MD 301 was made part of MD 290 when US 301 arrived in Maryland in 1940. Unlike
Interstate/Maryland number conflicts, US and Maryland number duplication was frowned upon in that
bygone era. By coincidence, US 301 happened to be rerouted to a path crossing the original MD 301 around
1960. US 301 ended in Baltimore from 1940-60, and Eastern Shore US 301 was MD 71 after being built in the late 1950s.

At one time, 303 extended north along current MD 309 in
Queen Anne's County to 213. What remoains of 303 today appears to be an
insignificant loop in northeastern Talbot County. The current section was
also once called Old Cordova Rd.

6.05 mi.; from MD 331/North Main St in Hurlock northeast to end of state maintenance at Charles St, Federalsburg.

Marked east-west.

Unsure if the official route continues past Charles Street on Academy Avenue to Main Street. The marker at Charles Street is the only one in Federalsburg on any route.
Learning bad habits from Baltimore.

Most of the Queen Anne's County segment was originally MD 303. A new type of road striping is being tried in the small hamlet of Starr, with a small median and painted brick on the sides to simulate a town road, as an attempt to get drivers to slow a bit. I need to get a photo of this. It's similar to some of the painted brick crosswalks I've seen in various Eastern Shore towns.

The southernmost tip of MD 309 was run along Black Dog Alley to form a T intersection with US 50 north of Easton. It also aligns with a new section of MD 662 directly across. This improves access to/from Easton for locals not using US 50.

At over 75 miles, MD 313 is the second longest state route, and 9th
longest overall, tracing a long path down the inland portions of the Eastern Shore.

The number has been the same as long as there has been numbering, which begs the
question if it was ever a US route. As far as can be told my answer would be no, but it was certainly
a candidate for US highway status.

The intersection with US 301 has been reconfigured. There is no direct access
to cross 301 anymore; one has to turn right on 301 and use a U-turn lane provided a short distance away,
then swing back for a right turn to continue on 313.

4.93 mi.; from railroad crossing at west end of Greensboro east to Delaware state line.

Marked east-west.

Western beginning of MD 314, Greensboro. (photo 02/21/10)

In Greensboro, the portion of 314 from 480 west to the railroad tracks was once MD 315. A new Choptank bridge for MD 314 was completed in 1995; this section, E Sunset Ave, along with N Main, was part of MD 313.

Two State Road, now a small spur near the state line in Whiteleysburg (MD 314A) was the original 314 which connected to DE 12. The small piece of Whiteleysburg Rd from Two State Road to the line was numbered MD 489.

You now have to make a left to end up on DE 12; going straight on Whiteleysburg Rd ends up being DE Road 59 (the secondary designation). DE 12 may still run along Two State Rd and connect to MD 314A, and although signed as DE 12, Burnite Mill Rd also carries DE Road 452. All Delaware routes, even if a signed primary route, also carry the secondary DE Road numbers. The primary route just overlays.

The pavement quality east of 313 is excellent. In Greensboro it's a bit rough and shows some cracks, but that's how I can tell if it was a state route; that's from the original pavement beneath.

Runs through the town of Federalsburg, which is bypassed by MD 313 and 318.
Although an east-west route, it is signed north-south. The only signed junction is at MD 318 east
of Federalsburg, 318 being longer and signed east-west, so I suppose it was signed north-south to contrast and
be 'perpendicular' with 318. There is a reference to the bridge over
Marshyhope Creek in Federalsburg as being part of MD 315, but all signage stops at the town limits.
No signage for 315 appears at the supposed western end along MD 313.

from railroad crossing at west end of Greensboro east to Main St (MD 480).

Route annexed by MD 314, number later reassigned.

The separate MD 315 in Greensboro, from the 1939 official SRC map.

The portion of 314 from 480 west to the railroad tracks was once MD 315.
This was likely before MD 313 was completed northeast of town, and 313 ran along E Sunset Ave and N Main St. Therefore, separate numbers in the no dual-number policy.

11.32 mi.; from MD 331 near Elwood east to DE line east of Federalsburg.

Marked north-south.

Between Elwood and Federalsburg, this route is the county line between Dorchester and Caroline.
This section was also once numbered MD 319. MD 313 & 318 are co-signed along the bypass south and
west of Federalsburg. MD 318 becomes DE 18 at the border.
